Hemocoagulation activity of fallopian tubes

Thromboplastic and fibrinolytic properties of uterine tube extracts of 48 cadavers of women and girls who died and died of various causes were studied. Among them there were 16 cadavers of children under 10 years old, 16 of women of childbearing age and 16 of 50-75 years old. Uterine tube extracts were prepared at the rate of 20 mg of tissue per 1 ml of physiological solution. Total coagulating and thromboplastic activity of the extracts was judged by their effect on the clotting time of bestrombocyte plasma during recalcification and prothrombin utilization in it. Addition of 0.1 ml of the extract of initial concentration reduced the clotting time of low platelet plasma and increased prothrombin utilization in it. Similar effect of uterine tube extracts in all three age groups persisted until their dilution of 50 thousand times. The obtained data indicate rather high thromboplastic activity of fallopian tubes, which is the same at any age.
